Brief description of the drawings
With reference to the description of the embodiment below in conjunction with accompanying drawing, above and other object of the present invention and feature will become more apparent, and can understand better the present invention itself, wherein:
Fig. 1 represents the communication network CN such as Access Network AN, has wherein realized the present invention.
Embodiment
In paragraph below, with reference to accompanying drawing, by describe according to of the present invention for manage Access Network AN multiple communication equipment CD1 ..., the realization of the method for CDx.At the first paragraph of this description, the main element of communication network is as shown in Figure 1 described.At second segment, all connections between said elements and the device of description are defined.In paragraph afterwards, the actual execution for the method for session establishment is described.
This Access Network AN comprise multiple communication equipment CD1 ..., CDx and multiple access unit, but, succinct in order to make to describe, select only to have an access unit AU.In the present embodiment, select Digital Subscriber Line Access Multiplexer, although also can select any other access unit.
In addition, there is the management server for managing communication devices.In the present embodiment, this management server MS is selected as configuration server, but can be also any attempt and communication equipment set up layer 3 IP device being connected.
Each communication equipment by ATM connect L1, L2 ..., Lx is connected to access unit AU, although can be that any other layer 2 connects, as Ethernet or MPLS.
Configuration server MS is connected to access unit AU by ATM, Ethernet or MPLS converging network.
For work of the present invention is described, suppose that each communication equipment does not distribute unique IP address, although the present invention also can be operated in the situation that all communication equipments have unique public ip address.In addition, suppose at a time, communication terminal need to be managed, for example, in the time operating for the first time, and configuration of communications device.
In the situation that user supposition manage based on IP, access unit AU sets up continuously configuration server MS and is connected to the IP connection between the communication equipment of access unit AU.But, in the time not having unique public ip address to distribute to terminal, can not set up IP and connect.
On the contrary, during communication equipment management phase, access unit AU sets up continuously with the interim point-to-point layer 2 discharging from access unit AU to each communication equipment and is connected.It is the interconnection connecting to the permanent layer 2 between access unit and configuration server (CS) that this interim point-to-point layer 2 connects.Set up configuration server MS and described multiple communication equipment CD1 ..., each described interim point-to-point layer 2 between the corresponding communication device of CDx is while connecting, configuration server MS uses the terminal identifier of corresponding communication device CD1, configuration corresponding communication device CD1.After configuration of communications device CD1, discharge the interim point-to-point layer 2 of setting up and connect.Subsequently, access unit is set up interim point-to-point layer 2 and is connected between configuration server MS and communication equipment CD2, afterwards by configuration server MS configuration of communications device CD2.In the time that configuration completes, the interim point-to-point layer 2 discharging between configuration server MS and communication equipment CD2 connects.Continuously each communication equipment being managed is carried out to this operation.
It should be noted that if apply asynchronous transport method between access unit and communication equipment, interim point-to-point layer 2 connection can be based upon on switch type virtual link.
In addition, it should be noted that, if apply the asynchronous transport method in converging network between described access unit and management server, interim point to point connect can be based upon on permanent virtual link, if or apply Ethernet converging network between access unit and management server, point to point connect can be based upon on virtual LAN VLAN pipeline, if or between access unit and management server, applied multiprotocol label switching converging network, interim point to point connect could be based upon in label switching path LSP.
The step that shall also be noted that the interim point to point connect of the each described communication equipment of continuous foundation from management server to described multiple communication equipments is the management data based on described access unit.
Terminal identifier can be the MAC Address of terminal, or any other unique identifier of communication equipment, as organization unique identifier (OUI).
Terminal identifier can be also the identifier of a group communication equipment, as the model of the vendor name of terminal and terminal and version.
It should be noted that the present invention can be applied in XDSL network, wherein communication equipment is bridge joint or routed modems, and access unit AU is Digital Subscriber Line Access Multiplexer.Link L1, L2 ... Lx is that ATM connects, and Digital Subscriber Line Access Multiplexer is connected to configuration server by Ethernet or ATM converging network.
The present invention also can be applied to mobile network, cable system or even in fiber optic network.
Finally note, above according to functional block description embodiments of the invention.According to the functional descriptions of above-mentioned these functional blocks that provide, for a person skilled in the art, how design uses the electronic equipment of the embodiment of very known these pieces of electronic components fabrication is apparent.Therefore do not provide the detailed architecture of the content of functional block.
In conjunction with specific device, describe principle of the present invention above, it should be clearly understood that this description only illustrates by example, instead of limitation of the scope of the invention, scope of the present invention is defined by claims.
